BAG-FILL N MACHINE.

Original No. 1,616,016, dated February 1, 1927, Serial No. 67,984, filed November 9, 1925.

y The invention relates to bag filling ma chines and more particularlyto a means for increasing the content by weight of the filled mg. the peculiar construction of means for compacting the material within the bag during filling operations as hereinafter set forth.

I In the drawings;

Figure l is aside elevation of the machine. Figure 2 is a, plan view thereof. .Figure 3 is a cross section.

In the filling of bags with granular material it is usual to place the mouth of the bag around the filling spout and to support the bottom on aishelf or platform. Where the material is discharged from the spout by gravity it would be loosely arranged and therefore greater .in bulk than when in a compacted state. Consequently it is difiicult to place within the bag the full quantity by weight which it is designed to hold. To avoid this difficulty I have devised my mechanism for imparting an oscillatory movement to the bag supporting platform such as to effect the compacting of the material by inertia and without displacement of the bag in relation to its support.

In detail" A represents the discharge spout from a bag filling machine of any suitable construction and B the bag to be filled having its mouthsurrounding said spout. C is a shelf or platform for supporting the bottom of the bag and D a vertically extending wall rising from said shelf against which the bag may rest.

The platform C and wall D are mounted upon an oscillatory frame comprising the horizontally extending parallel bars E shown as metallic angle bars. F is a link pivotally attached to the rear end of the bars E by a bolt or pivot pin G. H are stationary beams on opposite sides of the bars E and which support the link F through the medlum of a bolt I. J is a crank shaft extending transversely across the bars E and the beams H being journaled in bearings K upon said beams and having its cranks or eccentric portions engaging bearings-L on the bars E. M is a pulley mounted onthe shaft J and driven by a belt or other suitable dr1ve connection not shown.

\Vith the construction as described, it will p poted that the platform 0 a d W11 are .To this end the invention consists in 1927. .Serial No., 237,952.

supported on the forwardly projecting portion of the bars E, which in turn are supported by the crank J and link F. Thus,

when'the pulley M is .driven in the direction indicated by the arrow, an oscillatory move ment will be imparted to the bars E and platform C and wall D carried thereby.

Application for The direction of movement is such that when the platform changes from a downward to an upward movement it is also travelling outward but at decreasing velocity. Thus,

inertia will cause the compacting of the ma terial' againstboth the bottom and the rear wall and will, hold the bag from relative displacement. On the other hand, on the re-' versal from upward to downward movement, gravity will assist in overcoming the inertia or the displacement of the bag thereby. The total effect is to compact the con tent of the bag during the filling operation so that the full quantity maybe placed therein.

WVhat I claim as my invention is:

1. The combination with means for discharging material into the mouth of a bag,

of a support for the bottom and one side of the bagfand means for imparting to said support an oscillatory movement in a Vertical plane and in a direction to press the side support against said bag on reversal from downward to upward movement of the bottom support therefor.

2. The combination with means for discharging material into the mouth of a bag,

of a support for .said bag comprising a horizontally extending bar, a pivotal link for supporting one end of said bar, a revoluble crank for engaging an intermediate portion of said bar and a platform and side wall for engaging the bag mounted on the free end of said bar. I

3. The combination with means for discharging material into the mounth of a bag, of a support for said bag comprising a pair of parallel horizontally extending-bars, a swinging link for pivotally connecting and supporting the rear ends of said bars, a revoluble crank shaft for engaging the intermediate portion of said bars and a platform and side supporting wall for the bag mounted on the forward end portion of said bars.
